Hi! Many thanks for your reply. I no longer feel like I'm at a dead-end.

I am a Great-great-great-great grand-daughter of Thomas Beirne (1810). Where do you fit in?

Are you following the Dignan Beirne line? The Dignan name has kept cropping up but I kept disregarding it. Great to know Kitty Dignan is related by marriage to my people.
How much do you know regarding dates (birth, death, marriage) for these people? If so, are you able to share?

Lovely to hear from you!

Cheers
Kate
